Ji Shao, an aide to Emperor Jin Hui during the Jin Dynasty, was handsome and talented.

Once, when his country was being invaded, he accompanied Emperor Jin Hui in defending the country, but unfortunately they lost the war. Most of the soldiers died or deserted, but Ji Shao stayed with the emperor to protect him.

Upon seeing this, the people were moved and said: ”Ji Shao is like a crane standing among chickens, preeminent and superior.”

This idiom "鹤立鸡群" (A crane standing among chickens) is currently used to describe prominent people with good looks and impressive abilities among a crowd.
